How to make shrub roses bloom abundantly?
Let me tell you about the introduction of green plants and flowers on how to make shrub roses bloom abundantly. The following editor will answer your questions in detail.
How to make shrub roses bloom abundantly? Take action now, and the flowers will triple in autumn!
Many of our flower friends, after buying rose seedlings with flowers, will support the rose branches with a wooden stick to prevent the flowers from drooping or bending the branches due to the weight of the flowers. Especially for those who buy large藤本月季 seedlings, they will immediately tie the branches straight after receiving the seedlings, as shown in the figure below.
People always think that藤本月季 will grow tall like a tree with one branch. However, that's not the case. Of course, it's not recommended to buy such large藤本月季 seedlings. The reasons are written in the book "How to Raise an Explosive Rose from Scratch," and I won't elaborate further.
Today, I mainly want to talk about how to raise shrub rose seedlings to make them bloom abundantly quickly.
Techniques for quickly making shrub rose seedlings bloom abundantly
Here, we need to distinguish between the seedlings' conditions, as different conditions require different management focuses. Currently, the most common rose seedlings on the market are three types: nutrient cup toothpick seedlings, v9 pot seedlings, and 1-gallon large seedlings.
1. Key points for caring for toothpick seedlings
The key point for caring for nutrient cup toothpick seedlings is to focus on root growth and preventing diseases and pests. When planting, use small pots as much as possible, as small pots have a faster wet-dry cycle, which is beneficial for root growth. You can also occasionally water a little rooting powder to promote root development.
In addition to promoting root growth, preventing diseases and pests is very important. Since the seedlings are small and have weak resistance, once they are infected with black spot or red spider mites, the leaves will fall off or be damaged, and the seedlings will basically be in a dormant stage, with severe cases leading to withering. It is recommended to pay attention to comprehensive disease and pest control according to the characteristics of the breeding environment and seasonal features.
For example, indoor balconies need to focus on preventing red spider mites and black spot diseases. When spraying, fungicides and miticides can be used together. Additionally, in summer, when caterpillars are prevalent, insecticides for caterpillars should be used in combination. Detailed schemes for comprehensive disease and pest control can be found in the book "How to Raise an Explosive Rose from Scratch."
If it's really difficult, you can also use a rose care kit, which contains three types of agents. It can deal with common rose diseases and pests at once, which is relatively time-saving and labor-saving for beginners.
2. Key points for caring for v9 pot seedlings
v9 square pots have a diameter of 9*9 cm and generally have a growth time of over 8 months, with relatively strong roots, although still weaker than 1-gallon seedlings. Therefore, we cannot expect too much from such medium seedlings, especially for cuttings, whose roots are not yet strong enough. If you want them to grow quickly, one important point is to control flowering.
Flowering not only consumes nutrients but also reduces the growth time of new branches. Careful flower friends may notice that after rose seedlings produce flower buds, they seem to stop growing tall? This is because with flower buds, roses enter the reproductive growth stage from the vegetative growth stage, limiting the germination of new buds because nutrients are diverted to the flower buds.
Can medium seedlings not bloom? It's not absolute. If you can maintain very sufficient fertilization and watering, roses will also grow new buds while flowering. However, most of the time, we cannot achieve such fertilization and watering management.
Think about it, are you afraid of fertilizer damage if you fertilize every day? And can your potting soil achieve a wet-dry cycle every day? The wet-dry cycle directly affects the frequency of root top dressing. In addition to root top dressing, foliar top dressing should be done almost every one or two days, and no fertilizer damage should occur. This is a very difficult task for新手 flower friends.
Therefore, the suggestion is to control flowering, pinch off the flower buds when they appear. Now, the first batch of flowers has basically ended, and you can trim the residual flowers and shallowly bury fermented organic fertilizer or controlled-release fertilizer around the pot. Organic fertilizer is recommended to be used once a month, and controlled-release fertilizer can be used according to the duration of its effect. If the watering frequency is high and the potting soil is prone to compaction, microbial fertilizer can be used in combination to activate the soil and improve fertilizer absorption and utilization.
After shallowly burying long-acting fertilizer, it's also necessary to use fast-acting water-soluble fertilizer at least once a week. For those with high watering frequency, water and fertilizer can be alternated. When the seedlings grow vigorously, you can press the branches to promote the growth of new shoots. For specific methods, please refer to the branch pressing method for large seedlings below.
3. Quick blooming method for large rose seedlings
After large rose seedlings bloom in spring, if the plant shape is not very full, we can prune and fertilize like medium seedlings. After burying the fertilizer, pull the old branches horizontally to break the apical dominance of the branches, allowing the nutrients to flow back to the roots and making it easier for the bottom buds to germinate.
The figure above shows the branch pressing operation of a student in the flower wall camp, pulling the old branches to an angle close to hydroponics and then fixing them with hooks on the edge of the pot. By pressing the branches flat, two strong buds grew from the bottom of the plant. It should be noted that when the strong buds grow to about 10 centimeters, they should be pinched to promote branching and the growth of new buds. If not pinched, you will fall into a cycle of uneven and non-full plant shapes.
It is also important to note that during the branch pressing process, new buds may still appear at the top of the old branches. In such cases, it is important to remove the new buds promptly or pinch them to limit their growth.
By performing the branch pressing operation and pinching, we can quickly grow rose seedlings from two or three branches to more than ten branches, or even more.
What needs to be emphasized here is that throughout the branch pressing process, we need to maintain sufficient fertilization and watering. Without sufficient fertilization and watering, roses will not have the strength to grow. Therefore, before pressing the branches, we need to shallowly bury long-acting fertilizer. If this step has not been done, it's still not too late to make up for it now.
With long-acting fertilizer as a base and the addition of water-soluble fertilizer, roses will have the strength to grow. In addition, disease and pest control must also be kept up to prevent black spot and red spider mites from ruining all your efforts.
The above is a detailed explanation of how to make shrub roses bloom abundantly. I hope this article can bring you some help in green plant management!
